<p>A disc drive includes a drive mechanism 60 having an operative gear 65 rotated by a motor. The operative gear 65 carries out a first operation which moves a disc tray between a disc loading position and a disc eject position with a cam mechanism being held at the first position, when the operative gear is engaged with a first rack of the disc tray, and the operative gear carries out a second operation which displaces the cam mechanism between the first position and the second position when the operative gear is engaged with the second rack, thereby displacing a mechanism unit 42 provided with a turntable between a raised position and a lowered position. By constructing in this way, it is possible to provide a disc drive which has a simple structure formed form a small number of parts and which can be assembled with fewer steps. The mechanism unit is formed from a base frame 43 and a support member 44 which is supported on the base frame through three elastic members arranged at predetermined positions, thereby enabling to prevent vibrations generated by the rotation of the disc from being transmitted to the base frame, the chassis and the casing.</p> |
